Why can't radiometric dating be used with accuracy on metamorphic rocks?
An accurate radiometric date can be obtained only if the mineral remained a closed system during the entire period since its formation this is why radiometric dating can't be used with accuracy.
What evidence indicates our solar system is about 4.5 billion years old?
The age of the Solar System HAS TO BE at least as much as that of the oldest rocks found on Earth, other planets, or asteroids (if you assume that those rocks come from the Solar System) - and that's what has been found. And that's the approximate age of the oldest rocks found. The main methods used rely on radiometric dating. For more information, check the Wikipedia (or other sources) for:* Age of the Earth* Radiometric dating
Is the Hawk circulatory system open or closed?
Closed (I think. All vertebrates I know of have a closed system)
Are turtles circulatory system open or closed?
closed

What is the use of a metal lead relating it with uranium?
The system uranium-lead is very important for radiometric dating of rocks (ages between 106 and 5.109 years).
What radiometric system applies to the Jurassic time period?
The Jurassic is an age that began about 200 million years ago and stretched for about 50 million years to about 150 million years ago. Radiometric dating can identify certain materials as being from that period, but we don't have a "radiometric system" for the Jurassic, per se. Radiometric dating is part of the radiometric (from radioactive measuring) system we use to investigate a number of different things, including the age of materials found on the earth and elsewhere.
Why is a closed system necessary in radiometric dating?
Because you determine the ratio between different elements or isotopes. When one of the elements you are looking at is either added to or removed from your sample, this ratio gets distorted, and you won't be able to make a correct guess of the age of your sample.

What eons old is the world today?
Our Earth and most of the Solar System is about 4.5x109 years old. This is established by radiometric dating, commonly by the uranium - lead series.
Do amphibians have an open circulatory system or a closed circulatory system?

Is a Acid Rainfall open system or closed system?
Closed System
Do sharks have an open or closed circulatory system?
Brown bear have a close circulation system
What happen to mass and energy in a closed system?
In reality closed systems do not exist. In the theoretical case of a closed system the total energy of the system would stay the same (matter and particles are considered energy to). More important: the energy level throughout the whole system will eventually be evenly spread and uniform (entropy), therefore no energy differential is left to perform work.
Is a burning candle an example of an opened system or a closed system?
closed system
Should radiator be analyzed as closed system or open system?
closed system
